Sarcodon fuligineoviolaceus has a wide distribution in Europe and Asia and form ectomycorrhiza with various conifers in older forest on mostly on dry calcareous soil. Conspicuous and easily identified, much searched after and is an extremely rare species throughout Europe. It richest occurrences in Europe is in Sweden and Spain. The population in Europe population is very small and fragmented and with only a few mycelia at each locality. The European population is estimated to have declined, and continuing to decrease due felling of mature lime coniferous forest. It is very rare in Russia. It is widespread in China.
In Europe, it is nationally red-listed due to decline of older calcareous forests and the total population assessed not to exceed 10 000 mature individuals. There is no estimate of the population size in China and there it is nationally estimated to be of least concern. It is globally listed as Near Threatened.
ITS-sequences of S. collections from Sweden has been show to be similar with sequences of S. fuscoindicus from North America but are here considered as different taxa.
Sarcodon fuligineoviolaceus is distributed in Europe and Asia (China, India).
Conspicuous and easily identified, much searched after and obviously an extremely rare species throughout Europe. The population in Europe population is widely spread but small and fragmented and typically a few mycelia at each locality only. It richest occurrences in Europe appear to be in Spain and Sweden (Fraiture & Otto, 2015). The European population is estimated to have declined, and continuing to decrease due felling of mature calcareous coniferous forest. It is red-listed in at least seven countries. In Russia, it is only known from Sakhalin Island, < 5 localities (2018, Tatyana Svetasheva pers comm). In China it is documented in the literature from about 20 localities throughout the country (e.g. Sichuan) and is suggested to be classified as nationally Least Concern in the Chinese Red List of fungi (planned to 2018).
It is assessed as Near Threatened based on the criteria A2c considering that the status of the European population would be assessed as Vulnerable A2c+3c+4c, C2(ai) and considering the assessed stable status of the species in China.The lenght period of evaluation is 50 years (= 3 generations according to the recommendations of Dahlberg & Mueller, 2011).
It forms ectomycorrhiza exclusively with Pinaceae; e.g. mainly Pinus sylvestris, but also with Abies alba, A.cephalonica and Pinus sylvestris. It mainly inhabits nutrient poor dry calcareous soils (often superficially acidified) with thin litterlayer. In the Mediterranean and temperate regions it mainly occurs in pine forest, in the Alps - Abies forest are suitable habitat and in the northern European countries is mainly in older open Pinus forest (often with presence of Picea or in mixed forests of Pinus and Picea. Sarcodon fuligineoviolaceus is one of the Sarcodon species most strictly associated to calcareus soil.
The main threat is forest management, i.e. clear felling. As all Sarcodon species it is sensitive to eutrophication due forest fertilisation or atmospheric nitrogen deposition.
